constructions for. attaining the same are desir- Claims.

This invention relates to alabel attaching unit which is designed to be connected with a wrapping machine. I have heretoforeobtained Patent No. 2,244,140, granted June 3, 1941, relating to label machine for attachment or association with a wrapping machine, particularly of the character shown in a still earlier application, Serial No. 247,063, filed December 21, 1938, produced by myself, jointly with Howard B. Tuthill, now Patent No. 2,310,719, granted Feb. 9, 1943, which latter application referred primarily to wrapping loaves of bread though not necessarily restricted to bread wrapping alone. In the present invention the label machine is a substantially independent unit in itself which may be connected and associated with many and varied types of wrapping machines and is not restricted in use to a. wrapping machine of any particular construction and operation.

Loaves of bread and other articles which are wrapped for protection preferably should be labeled, and the present invention is in connection with a label attaching machine usable with the wrapping machine and with which, simultaneously with the wrapping of each article, a label is applied and connected to the wrapper. The label may carry certain indicia such as the name of the article, and the producer, its date of wrapping and advertising with respect thereto and the like.

A primary object and purpose of the presen invention is to provide a label attaching machine for connection to, or association with a wrapping machine for attaching a label to each article wrapped so that when passed through the wrapping machine each article will be complete both as to wrapping and labeling. A further object of the invention is to provide a complete machine unit insofar as the labels and their attachment is concerned which requires for its operation in connection with the wrapping machine to which it is connected or with which it is associated only the operation and closing-of a switch in an electric circuit by a moving part in the wrapping machine, which moving part of the wrapping machine will close the switch once with each cycle of operation; and by cycle of operation is meant the cycle of operations which carries through the wrapping of a single articl in the wrapping machine. It is further to be understood that the independent label attaching machine of the present invention may be utilized to attach labels to wrapped articles or packages with slight changes or modifications.

Various other objects and purposes and novel ably produced by my invention, including novel means for changing the time of deposition of the labels, one after another upon the wrapping paper which is going to the wrapping machine, required when loaves or articles of different sizes are to be wrapped in the wrapping machine; a machine as an independent unit having its own power unit or prime mover to operate the mechanism for feeding the labels to the wrapping paper or to a wrapped article; a novel means for applying heat for securing individual labels-to the wrapping paper at properly spaced apart distances in its length; and many other novel arrangements and association of parts for practically and emciently controlling the deposition and application of the labels to the wrapping paper, reference being had to the accompanying drawings disclosing such embodiment, in. which,

Like reference characters refer to like parts in the diiferent figures of the drawings, and the sectional views are all taken looking in the directions indicated by the arrows.

The wrapping machine frame I, shown fragmentarily in Fig. 1, at an end thereof has a .tending from the frame I.

horizontal supporting bracket 2 secured in place, upon which the label attaching machine ofmy invention is to be supported. Said machine has spaced apart end frames 3 with adjustable foot members 4 which rest. upon the upper side of the bracket 2. A vertical bracket 5 is bolted above the bracket 2 at the same end of the wrap- It is of course to be understood that the label attaching machine does not necessarily require a direct physical connection to the wrapping machine so long as it is properly positioned with relation thereto andis maintained in such position.

. The wrapping paper 3 which is to be used for wrapping loaves of bread or other articles in the wrapping machine is mounted in a rollon a suit able shaft 3 carried by brackets Ill (Fig. 1) ex- The paper is led upwardly to and over a roller II on a suitable stantially the same horizontal plane and extend between the end frames 3 of the machine.

The label strip after passing over the upper part of the roller 30 is carried to and over a drum 35 rotatably mounted on a fixed rod or shaft 36 extending laterally from the upper end of the supporting post 32. The drum has two series of pins 31, each series being four in number, which shaft mounted on and extending between the end frames I on the machine (Fig. 3) which roller is located between theupper and lower ends of said frames 3. The paper is directed by said roller over-a horizontal plate l2 of sheet metal which overlaps a horizontal table l3 carried on and above an angle cross bar l4, to which a second angle cross bar i5 is bolted or otherwise secured as shown in Fig. 3. The edge of the table l4 nearest the wrapping machine comes closely adjacent a roller .IB rotatably mounted on the shaft 1 which is a fixed shaft with a roller l3 rotating about it. The paper 3 is carried over the upper side of the roller l6, thence downwardly underneath an adjustable roller l1 and therefrom into the wrapping machine over a drum l8 which is a. part of the wrapping machine.

The roller I1 is car-ried by and between the end portions of two spaced apart arms l9 (Fig. 3) fixed to a horizontal rock shaft 20 which extends between the end frames 3 of the machine. Shaft 20 carries a worm wheel sector 2| (Fig. 1) which is engaged by a worm 22, said sector and worm being housed within a housing 23 secured tion of turning the crank and thus change the position of roller l1.

A spool 26 is mounted for rotation on a horizontal rod 21 which is supported at one end by a substantially uprightarm 28 extending down to and connected rigidly with the fixed rod or shaft 1 (Fig. 2). The labels 29 are wound on the spool. Said labels are connected together with spaced slots 29a extending inwardly from each edge of the label strip toward each other as shown in Figs. 2 and 12, a complete label being located between consecutive pairs of slots 29a. The continuous length or strip of labels is carried from the spool upwardly over a roller 30 mounted on a rod 30a extending from the free end of a horizontal arm 3| which extends from a vertical casting support 32 at its lower end mounted upon two spaced parallel rods 33 and 34 being fixedly secured to the rod 33 to prevent lateral movement. The rods 33 and 34 are located in subproject radially therefrom and are located at intervals around the drum. The distance be-' directly over the'roller 30, it is permanently secured to a U-shaped stirrup 39, the legs of which are turned downwardly and are pivotally joined with the rod or shaft 30a on which the roller 30 is mounted. Thus the member 38 may be turned upwardly about the axis of the rod 30a in threading a new label strip through the machine over the drum 35,- and returned to place after the strip has been passed over said drum.

An endless chain 40. passes around a sprocket wheel at one end-of the drum 35 and also around a second sprocketwheel- 4| (Fig. 4) pinned to a horizontal shaft 42 which is located a short distance above and inwardly of the rod.33 (Figs. 3 and 4).

Arsecond drum 43 like the drum 35 is mounted on and secured totheshaft 42 and it likewise has two series of pins 44 extending radially therefrom and spaced at 90 intervals for entering the slots 29a in the label strip. The drum '35 is driven from the shaft 42 through the sprocket and chain connection described at equal speeds.

The label strip passes downwardly in a. substantially vertical plane from the upper drum 35 to the lower drum 43; and each label may be printed with desired indicia during such passage. A backing member *45 against which labels are pressed in printing is mounted at the upper end of a vertical post 46 which through suitable connections is permanently secured to the rod 33.

Theprinting unit is disposed to a side of the.

backing member 45 with the label strip passing between. The immediate printing plate or other type carrier 41 is normally disposed a distance from the label strip, as in Fig. 3, and is mounted in a guide fork of the frame 43 of the printing unit. A rod 49 actuated by a spring 50 to normally withdraw the part 41 is guided through the printing frame. A second rod 5! is slidably mounted in suitable guides on the printing frame and is connected at one end .by a link 52 with the rod 49. At its other end a link 53 connects it with the armature 54 of a solenoid 55 the energizing of which draws the armature into the solenoid and moves the immediate printing mechanism to the left (Fig. 3) compressing spring 49 and bringing the immediate printing plate 41 against a label: and forcing the label against the backing plate. The automatic closing of a switch in an electric circuit which includes the solenoid winding 55 inproper timed relationship with the intervals of rest between successive step by step movements 'of the label strip will be hereafter described.

Shaft 42 is provided with a sprocket wheel 56 (Fig. 7') toward one end thereof to be driven by an endless chain 51 which also engages with a second sprocket wheel 33 on a horizontal stub shaft 89 mountedon one end frame 3 of the machine (Figs. 2 and 9). The shaft 59 at its outer end carries a ratchet wheel 30 (Fig, 9) which is necteda distance from the center or a disk 65.

secured to a short shaft 36 mounted on the same end frame 3. The .rotationof the disk 65 reciprocates the connecting rod 63 in a manner similar to a pitman operation. The disk 65 being designed to be operated for single rotations with intervals of rest between, at one side of the disk it is provided with a shallow recess or flat 81 against which a roller 93 may bear at times. The roller 68 is carried at, one end of a pivotally mounted arm 69 pressed by coiled spring 19 (Fig. 9) so as to force the roller 68 against the edges of the disk 65 and cause the disk at the end of asingle complete'rotation to come to rest with the roller 68 engaged against the portion 67 of the disk.

At the inner side of the disk 65 (Fig. 9) a short laterally extending roller II is mounted which in the counterclockwise rotation of the disk, as inthe armature is moved upward with a corresponding upward movement of the bar 91 at the end connected therewith, which causes the yoke 85 to be turned about the pin 86 and move the movable clutchmember 19 into engagement with the 'fixed clutch member 8|.

The label strip 29 afterpassing downwardly and under the drum 43'is directed downwardly and inwardly into the machine underneath a roller 92 which is loosely mounted for rotation on the rod 34. It is to be understood that the rod 34 is fixed at its ends in' the end frames ,3 of the machine like the rod33. The drum 43 and the roller 92 are grooved at 'spaced distances (Figs. 4 and 5) for endless belts 93 to pass therearound for driving roller 92 from the drum 43.

An angle bar 94 is provided with inturned arms 95- (Fig. 2) pivotally mounted upon the shaft or rod 34 and normally extending upwardly and away from said rod or shaft. To one of said' arms at one endof the bar 94 a sleeve 96 is secured (Figs. 2land '7). through which the rod 34 passes, and, from which an arm .91 extends equipped with a roller 98 which. rides upon a cam 99 fixed to the stub shaft 66. 'The cam 99 has a short depression or recess I09 (Fig. '7) and a muchlonger depression or recess. m immediately thereafter, the remainder of the edge of r the cam, which is in the form of a disk, being dicated by the arrow, engages a pivotally mounted switch closer i2 for an electric switch i3 and thereafter a second switch closer F9 for an electric switch '55. The switch at E3 is to be located in the electric circuit which contains the solenoid winding 55 to close such circuit and operate the printing mechanism. The switch 15 is in a different electric circuit shown in Fig. 10, the function and operation oi which will hereinafter appear.

Theshaft 66 on which disk 95 is secured is driven by an endless chain it engaging with a sprocket wheel Tl secured to the inner end of the shaft 99 (Fig. 7), which chain also passes around a second sprocket wheel '79 integral with or permanently connected to a movable clutch member "i9 on a shaft 99 (Fig. 8) which clutch member is movable into and out of engagement with a second clutch member 8i fixed to said shaft. Shaft 89 extends into a housing 82 which houses suitable worm gearing interposed between the shaft 89 and the shaft 99 of an electric motor 84 to greatly reduce the speed of rotation of the shaft 99 with respect to the high speed of rotation of the motorshaft. When the machine is in operation the electric motor 99 is running continuously, but the shaft 96 and the parts driven and operated thereby are in movement only when the clutch members 19 and 9! are connected.-

The movable clutch member 79 is grooved at one end (Fig. 8) for engagement with a yoke 95 which is pivotally mounted between its ends at 89. A bar 3? is connected at one end to the upper end of the yoke 85 and at its other end a vertical rod 89 passes freely through the bar. The rod 88 at its upper end is connected-with the armature 89 of a solenoid 90. Rod 88 below the bar 8'! has a light coiled spring 9| around the arc of a circle. With the roller 99 ridin upon the circular edge of the cam of greatest radius, bar 94 is slightly depressed momentarily when the recess I00 comes thereto and then upon reaching the recess at .Hll it is depressed a much greater extent and for a longer time,

oruntil the cam has moved far enough to'carry said recess ilii past the roller 99.

the completion of an electric circuit including it,

A heater W2 is yieldingly mounted by rods 893 with coiled springs therearound at the under side of the bar 94 and said heater in the lowermost position of the bar 94, or when the roller 99 is traversing the recess ii, is brought to a down position to press against a label lying upon the upper side of the wrapping the table it. v

Lying over the rod 34 is a short angle bar i114 having downwardly extendings arms M5 pivotally mounted upon said rod. --The upwardly extending leg of the bar I04 carries an adjustable screw it, an end of which comes against a boss 8971 at the upperside of the bar 95." A metal finger B99 is attached to the under side of the bar 899 and extends toward the heater and thence downwardly to one side thereof and terminates in an inclined terminal finger m9 underneath which the labels pass to the upper side'of the wrapping paper. The end labels are severed one after another from the label strip and one at a time during the operation of the machine, and when the roller 98 momentarily enters the recess m9 of cam 99 the finger 19 engages against the upper side of the label which is to be severed from the label strip and holds it against the paper during such severing and during the period the heating unit comes to its lowermost position and presses against the upper side of the label, supplying it with heat and cementingit to the wrapping paper. Of course it is to be understood that the under side of the labels engaging the upper side of the wrapping paper are suitably treated so that on heat being applied they will be cemented to the paper.

Two spaced apart. sleeves H9 are located around the rod 34 and fixed'thereto (Fig. 11) from which arms Ill extend in one, direction paper 8. over nently secured thereto, having a cutting edge extending slightly beyond the ends of the fingers II2. Such cutting edge is located a short distance below the path of the wrapping paper 8 through the labeling'machine. (Fig. 3). As also shown in Fig. 3, the label strip when passing from underneath the roller 32 goes between two spaced apart thin ,guide plates. (notnumbered) which are located between said fingers I I2.

A horizontal rod-"I14 extendsbetween the free ends of the arms. I I I on which two spaced apart bell crank levers are pivotally mounted each having an upwardly extending arm I-I6. anda downpivot I33 and the roller I3I (Fig. 6).

wardly and inwardly extending arm II6. A'sh'aft II! is mounted between thelends of thelower arms H6 and carries rollers II8 which come against the roller 82 at the parts thereof between the grooves so thatthe label strip is drawn between the upper and lower rollers 82 and H8.

Bars H0 are 'pivotally'connected to the'upperends of the. arms I.I6 ,are''reduced in size at a distanceaway therefrom and pass through'openings in the upwardly-extending leg of the angle bar I04, with coiled compression springs I20 between the bars IIland the angle bar I04 which act to yieldingly press rollers II8 against roller 92. Gears I2I on'roller'82 and shaft II'Idrive said shaft II'I 'fromtheroller" 92 so that the peripheral speed of all ofthe rollers that engage second bar a cutting blade I24 is secured which in its upper position' is located over thelabel strip so that on downward movement it will engage with the label strip between two oppositely disposed slots 29a therein and in conjunction with the lower knife II 3 will cut the end label from the strip dropping it onto the wrapping paper in a position substantially under the finger I09. The knife frame is an open frame and betwen the ends I23 thereof the heater I02 may move upwardly and downwardly. At its ends it is provided with downwardly extending arms I25 pivoted on a cross' rod I26. A pin I2'I extends from one of theend bars I23 (Fig. 8)

and carries a roller I28 which. rides on a second with 8. depending stem I36 which rests upon the upper side of the bar I32 at a point between the When the outer end of the bar I32 is depressed the stem I36 of the switch following thebar causes a bridging of the contacts I36a and I 36b to complete a break in an electric circuit (Fig. 10). At the inner end of a bar I32 a Z-shaped finger I31 of sheet metal is attached, the terminal flange of which extends below a flange oi the bar 04 (Fig. 6).

In the wiring circuit, diagrammatically illustrated in Fig. 10, a make and break switch I38 is used which is mounted upon the wrapping 0 machine frame (Fig. 1). It is not particularly important exactly where this switchshall be placed, so long as it is in thepath of movement of an element of thewrapping machine which will actuate the switch once during each cycle ofthe wrapping machine. As shown in Fig. 1 it it passes by-itand for an instant cause the switch to close to bridge the contacts I380. and

I38b (Fig. 10).

With the wiring diagram shown in Fig. 10, the wire I 4'I coming from a source of electrical energy, for example, .the positive side of a battery or any othe -suitable source, is connected with oneend of the winding of the solenoid 90.

The other end of the winding is connected by wire I42 with a contact I43 which is one of the contacts ofa relay switch conveniently mounted on themachine, as indicated at R in Fig. 9. The other wire I44 from the negative side of the battery or other source of energy connects with a contact I45 associated with and spaced from the contact I43, the space between said contacts to be bridged by a bridging bar as later described. A wire I46 leads from the contact I38a of switch I38 to one end of a solenoid winding I4'I forming a part of the relay switch R, the

other end of the winding being connected by a disk-like cam I29 securedto the shaft 66. Cam

I20 is a circular disk except for a concave depression I30 of relatively'short length (Fig. 7) into which the roller- I28 momentarily drops, at which time the knife blade I24, moves downwardly and across-the label strip to sever a label followed by an immediate return to its upper normal position; .In practice the frame I24 is actuated by a tension spring (not shown) which tends to pull it in a downward direction and holds the roller" I28 against the edge of the disk I29 and causes it to enter the recess I30 when reached. 1 i

Directly over'the rolle'r'II. around the upper portion of whichthe wrapping paper 8 passes (Figs. 3 and 6) a roller I 3I is located and between which and roller II the paper passes. The

roller I3I is eccentrically mounted at 'the end of a bar I32 which is pivotally mounted between its ends at I33 on a switch housing I34 clamped by means of clamping members I36 on the rod 34. The switch housing has a switch therein wire I48 with the return main wire I44.

A wire I49 connects the first mentioned main wire I4I with a wire I50 which at one end is i two spaced apart bridging bars I64 and I55, one

of which is to bridge the space between contacts I43 and I46 and the other between the contacts I6I and I56 spaced therefrom, which latter'contact is connected by wire I51 with one of the spaced contacts of the switch I6. The other contact ofswitch I6 is connectedby the wire I68 withthe wire I46 substantially at the point of juncture of said wire with one end of the solenoid winding I41.

Operation With the machine as disclosed, the wrapping paper 8 in the operation of the wrapping machine is drawn through the labeling machine to supp y wrappers for the articles, such as loaves of bread or any other articles to be wrapped.

The movement of the wrapping paper actuates the roller I3I to cause a bridging connection beslip underneath such roller I'3I, the switch re-.

maining closed until a cycle of the machine has gone through as hereinafter appearing.

The electric motor 84 continuously operating does nothing further until the clutch parts 13 and 8| are connected. This will occur when switch I38 is closed. With the switches I38 and I38 closed current through the wires I43, I43 and I53 passes the switch I38 and through the wire I52, goes to and passes the switch I38, following therefrom through wire I48 to the solenoid I41 and therefrom through the wire I48 to the other main wire I44 of the electric circuit.

The closure of the switch I38 will be but mo- Shaft 53 in its partial revolution driving the chain 51 (Fig. 7) will drive the shaft 42 part of a revolution. The pitch diameter of the wheel 53 being twice that of the sprocket wheel 53 one label, or that between two consecutive pairs of slots 23a.

The printing mechanism is operated by closing -the switch at 13 when the roller 1| comes to its actuating lever 12 (Fig. 9). That is, the label mentary, since the roller I43 will quickly pass by after its closing operation on switch I38. But while switch I38 is closed the solenoid winding I41 (Fig. 10) will be energized, causing the armature I53 to move and carry the bridging bars I54 and I55 into bridging engagement respectively with the contacts ,I43 and I45 and the contacts I53 and I5I. The connection of contacts I43 and I45 will complete a circuit through the wire I43, the solenoid winding 33, the wire I42, bar I54 and the return wire I44. This will operate the armature 83 to bring the clutch'members 13 and 8| into operative connected relation. Likewise the engagement of the bar I55 with the contacts I53 and I5I will complete another circuit, the current flowing through wires I43, I43, I53, bar I55, the wire I51, through the switch 15, wire I53, solenoid winding I41, wire I48 and the return wire I44. In this way a continuance of current through the solenoid winding I41 is insured after switch I33 opens. Therefore, the

strip will be at rest when the printing unit is operated and the printing unit will return to its initial position by the time the dog 64 engages with a tooth of the ratchet wheel 83, causing movement of the label strip the described distance to bring the next succeeding label into position for operation thereon by the printing mechanism. It is of course to be understood that the circuit for the printing unit is an independent circuit, is of simple form containing only thesolenoid winding 55, switch 13 and a source of electric energy connected by wires, that the switch 13 is normally open and is closed momentarily when roller 1I engages the switch closing lever 12. Furthermore, if labels which have been previously printed are to be used this circuit may be interrupted, for example, by disconnecting a wire, so that the printing unit will not operate during operation of the machine. Therefore, the printing unit is available selectively for use or non-use as conditions may require.

The rotation of shaft 38 likewise rotates the two cams 33 and I23 secured thereto through one revolution. The rotation of the cam I23 controls the operation of the knife blade I24 cutting off the end label when roller I23 comes to the recess I33 (Fig. 7-) and returning the knife blade to upper position substantially instantane- 'ously after the roller leaves such depression.

solenoid 33 will continue to receive an electric current and will hold the clutch members 13 and BI together as long as switch 15 is in closed position. Normally switch 15 is in closed position and is opened only when the roller 1I (Fig. 9) in the counter-clockwise rotation of the disk cam 35 strikes the switch actuating lever 14. For example, in Fig. 9, the roller has immediately previously engaged said lever and opened the switch, thus breaking the circuit supplying the solenoid winding I41 so as to de-energize the solenoid with a lowering of the bridging bars I54 and I55 which automatically breaks the circuit supply current to solenoid 33, whereupon clutch members 13 and 8i are disengaged, a cycle of the machine having been completed.

During this cycle of the machine with clutch members 13 and 8| in engagement, shaft 88 is rotated through one revolution. The clutch members 13 and BI remain in connection during one complete revolution only of the shaft 33, the sprocket wheels around which chain 18 passes (Fig. 8) being of the same diameter (Fig. 7). Such one revolution causes a single step movement of the shaft 53 through the dog 84 and the ratchet wheel 83. That is, with the parts in the position in Fig. 9, the disk 55 rotating counterclockwise moves the dog 84 from the tooth of ratchet wheel 83 with which it is engaged counter-clockwise to the next adjacent tooth and then reciprocates the connecting rod 83 in theopposite direction, moving the ratchet wheel clockwise one step or one-eighth of a revolution.

The recess I33 in the cam 33 comes to the roller very slightly befdre the knife blade operation with a slight lowering of the bar 34 and a release of the bar II4 which, under the influence of the springs I23, will turn slightly in a clockwise direction bringing the finger I33 into yieldin pressing engagement against the end label slightly before it is severed from the label strip, insuring that the label'will stay in position with respect to the paper 8 during the cutting operation and will not accidentally or aimlessly move to an undesired position.

The roller 33 has the longer depression I3I brought to it with a consequent clockwise swinging of the bar 34 and its end arms 35 to lower the heating unit I32 against a severed label lying on the paper. The heating unit is preferably heated by an electric resistance coil and is divided at one end to pass at either side of the narrow spring finger member I33I33 substantially covering the label which is held by the terminal finger I33 against the paper with a consequent cementing of the label to the paper at the outer side thereof. In the finished wrapped article the label applied to the wrapper will be at the outer side and away from any of the contents which is wrapped.

The switch I36 will remain closed during the cycle until the heater is lowered for its label cementing operation. When the switch I36 is closed by a lowering of the outerend of the bar I32 there is a corresponding lifting of the finger I31 at the inner end of the bar. The clockwise rotative movement of the bar 94 when the heater is lowered causes a flange thereof (Fig. 6) to engage said finger I31 thereby lifting the outer end of the bar I32 and elevating the switch I36 to break its connection with the contacts I361: and I362) until the switch is again closed by the movement of the wrapping paper 8 rotating the roller I36 counter-clockwise a sufilcient distance to again lower the bar I32 so that the switch is again closed, putting the machine in condition for a succeeding cycle of operation when switch I38 has been closed by the action of a moving part in the cycle of operation of the wrapping machine itself.

The adjustment of the roller I'I changes the relative positions of the labels one after another deposited on the wrapping paper. For example,-

when the labeling machine is associated with a bread wrapping machine, a change in the size of the loaf to be wrapped requires a change in the adjustment of the wrapping machine to provide a different length of wrapper; and in order to have the label properly appear on the wrapped loaf it must be correspondingly adjusted to be properly deposited and securedto the paper, one

of such labels for each wrapper used with each plete roll after the labels are attached or cut into sheets each with a label attached for sub- In such case sequent use in wrapping articles. there is required only association with a machine to trip the switch I38 at adjustable properly spaced or timed intervals which mechanism does not need to be an entire wrapping machine. Furthermore, articles which have been wrapped and desirably should be labeled may, through a modification of this machine, have such labels attached, feeding the wrapped articles through the machine in a manner similar to the way the wrapping paper is drawn through the machine, said articles being stoppedin movement periodically at the proper points to receive and have attached the label. I Q

With the present machine the wrapping paper isdrawn into the wrapping machine with stop intervals between movements, of' the wrapping paper. That is, a length of the wrapping paper suflicient to wrap a single article is. drawn into the machine cut from the roll andzis usedto wrap a loaf of bread or other article. In the operation of the wrapping machine, for example,

tion of myself and Tuthill jointly, such periodic movements of the paper takes place. The present labeling machine deposits and-cements the of construction coming within the scope of said claims.

I claim:
